Explanation of Responses:

( 1 )On April 22, 2020, issuer granted to the reporting person 142,228 restricted stock units (RSUs), subject to receipt of required approval of an amendment to issuer's 2016 Equity Incentive Plan to increase the number of shares authorized for issuance under the plan by at least such number as is necessary to vest all of the awards granted on April 22, 2020. The RSUs vest in three equal installments on each of the first three anniversaries of the grant date; provided, however, that the vesting of 50% of these RSUs is subject to the additional condition that the publicly-traded stock price for the issuer's common stock reaches a 30-day average trading price equal to or above $7.52 per share during the first three years following the grant date. Should the publicly-traded stock price for the issuer's common stock reach a 30-day average trading price at or above $7.52 per share at any time during such three year period, this pricing condition will be satisfied and will terminate. ( 2 )Each RSU represents a contingent right to receive one share of the issuer's common stock.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
